FM reception - aftermarket HU - 5th gen
yo homies
got my aftermarket stereo stuff installed (replaced bose) and now it seems like i get mostly bad reception, i have a 2002 and for some reason there is no antenna on these things, maybe its hidden in the back window or somthing i dunno
did they do somthing wrong or do other people have this problem
also when they integrated my steering wheel controls when i hit the track up button it always skips 2 ahead, but the down button works fine, so thats why im thinking maybe its the installers but i wanted to make sure it wasnt a known maxima issue

Supposedly this is a problem with all aftermarket HUs. Our cars have the antenna in the rear window. The 2-pin system is apparently designed to work with the stock HU because it has special tuning built-in that properly combines the two signals to produce "good" reception. Aftermarket HUs are designed for regular antennas and do not have the special tuning required to decode the signals or whatever from the stock antenna in these cars.
I believe the only thing you can do is install a separate aftermarket antenna.

did anyone try this guy's workaround?
the antenna adapter is behind the HU right in the dash?
ill have to tell the installers to give it a wing

i had the exact same problem, and i saw a thread on here and i fixed it. im not sure if i am describing it right, if you have the bosch wiring unit and you connect all the wires together i think there is a subwoofer wire that is not connected to anything, and it tells you not to connect it. well if you connect it to the ground wires then the radio works fine.
again im not sure if it is a subwoofer wire or what it is, but that was the problem for me and a handful of other guys on here.

could it be the dimmer negative wire?

no more noise
after market antenna didn't solve the problem. Make sure to ground the HU to itself, providing same ground as power antenna since there's no ground in factory wiring and grounding to the back chassis didn't provide common ground with the antenna. it's not a diversity antenna issue since it has the window antenna in addition to the regular antenna and if you use the after market antenna adaptor, you are effectively using the regular antenna unless you reverse the adaptor as one OP suggested.

i have a 3rd gen. maxima and an eclipse head unit. I was thinking about listening to just FM radio. So you guys think that I'm gonna get crappy reception with the Eclipse head unit? If so, what should I do? Should I try to buy a 3rd gen. stock radio receiver? Or should I try to change my stock antenna and keep the Eclipse?

On your metra/scosche wiring harness, make sure the solid blue wire is hooked up to the blue/white wire coming out of the aftermarket head unit. Thats the power antenna wire, and by connecting it to remote turn on you are essentially "amplifying" the signal, in not so many words.

I've never had any problems with fm reception.
Here is how my setup is like, maybe that will help some of you:
-Eclipse cd8454 / 8455 - both get good reception
-Grounded to chasis - there are two nuts at the bottom of the dash when you pull the radio/climate assy out, I unbolted one nut and grounded my hu over there along with my pac swi-x Picture of my grounding point
-I'm using some antenna adapter which converts the nissan 2 pin plug into a single plug for my hu to accept. I dont know what brand it is. There were two of them there because the dealer installed a pos fm modulated 12 disc cd changer instead of the bose 6disc when the car was purchased new. I only ended up using one of them. Picture of my antenna adapter
-Power antenna wire from hu is connected to power antenna wire from metra harness.

yeah, but the highest Eclipse HU has a S/N ratio of 100 db, so even if CDs are 120 db, unless the decoder has a S/N ratio of 120 db, you won't be enjoying the CDs to the fullest.

I bought my 2000 Max back in March and it had an aftermarket HU with very bad reception on all stations. I took it to the stereo store to get it fixed. They said that the diversity antenna in the back glass had a antenna amplifier or booster that did not have the turn on lead connected to the aftermarket HU. They connected it and now I have great reception.
